SPEOIFIGATION forming part of Letters Patent No. 278,479, dated May 29, 18-83.

Application filed March 14, 1883. (No model.)

Toall whom it may concern:

Be it known that I, AROALOUS WYoKoFF, a citizen of the United States, and a resident of Elmira, in the county of Ghemung and State of New York, have invented certain new and useful Improvements in Vehicle -Wheels, of which the following is a specification.

My invention relates to that class ot'vehicles supported by annular wheels; and it consists in constructing the parts, as 'fully described hereinafter, so as to hang the body low down, reduce friction, and avoid obstruotin g the entrance to the vehicle.

In the drawings, Figure 1 is a side elevation 1 of a vehicle, showing my improvements. Fig. 2 is a sectionalelevation; and Fig. 3, adetached section, showing a modification.

The body A of the vehicle is of any suitable character and construction, and the side sup- 2 o porting-wheels consist of rings B Bof metal, which extend slightly'below the body, in each side of which, within the circle of the wheel, is a doorway, to. To each side,within and concentric with the wheel, is firmly secured an 2 annular hearing or ring, 0, and between the latter and the wheel is arranged a series of flanged friction-rollers, b I), each of which turns j on a pin projecting from a carrier-ring, D. The annular ring B is thus confined upon the annuo lar bearing 0 by the flanged rollers, which travel freely between the two, permitting the wheel to revolve easily and with but little frictiOllj. As the rollers travel with the Wheel, they hawe no bearing upon their pivots,which serve 3 5 merely to maintain them in their relative positions. l i a By theoonstruetion described the entrance to ithevehicle free from any obstruction, the

bearings for the wheels being all outside of the rings O,so that danger otsoiling the clothin gin entering orleavingthe vehicle is avoided.

By the use of the annular bearings, as set forth, I am enabled to secure spring-bearings for the wheels, springs 0 being interposed at any suitable points between the rings 0 and 5 the brackets s on the body of the vehicle.

Instead of using flanged friction-rollers, the rings B C may be grooved on their adjacent faces to receive spherical rollers, as shown in Fig. 3. go

I claim I l. Theeombination, with a vehicle, of annular bearings O, secured to the sides thereof, annular wheelsB, revolving round said bearings, and interposed friction-rollers, substantially as specified.

2. The combination of the annular inside stationary bearing, concentric annular wheel, and interposed rollers turning on pins projecting from carrier-rings D, substantially as set 6o forth. x

3. The combinationof the annular bearing, annular wheel, and flanged rollers interposed between them, substantially as set forth.

4. The combination of the friction-rolls, annular bearing, and springs interposed between the latter and the vehicle, substantially as specified.

In testimony whereofIbave-signed my name to this specification in the presence of two sub- 70 scribing witnesses.
